I assume you can rewrite the code from switch to if/else before compiling with go/ast package. If that is not your case, hacking the go compiler is a harder solution, you probably don't want to do that.

I tried with *"go build -gcflags='-N -l''"* but I still have jump tables like *"switchD_004010a2::switchdataD_004bc900"* with cases like *switchD_004010a2::caseD_11* ; *switchD_004010a2::caseD_12*... that are in the .rodata section. Those don't sound like jump tables generated by the Go compiler. Does your program use cgo? Might they be from the C compiler? @Ian, ok I understand thank you. I am working on Go binary analysis and this feature would help a lot.

Sorry, there is no such option for the usual Go compiler. Why do you want it?
